The DNS servers would tell the browser to use some specific **IP address**. That would be the public IP address used by your server, that you configured in the DNS servers.

### TLS Handshake Start

The browser would then communicate with that IP address on **port 443** (the HTTPS port).

      InetAddress ip = InetAddresses.forString(validIsatapAddress);
      assertTrue(InetAddresses.isIsatapAddress((Inet6Address) ip));
      assertEquals(
          "checking '" + validIsatapAddress + "'",
          ipv4,
          InetAddresses.getIsatapIPv4Address((Inet6Address) ip));
    }
    for (String nonIsatapAddress : nonIsatapAddresses) {
      InetAddress ip = InetAddresses.forString(nonIsatapAddress);

你可能拥有一个云服务器（虚拟机）或类似的东西，并且它会有一个<abbr title="That isn't Change">固定</abbr> **公共IP地址**。

在 DNS 服务器中，你可以配置一条记录（“A 记录”）以将 **你的域名** 指向你服务器的公共 **IP 地址**。

这个操作一般只需要在最开始执行一次。

     域名这部分发生在 HTTPS 之前，由于这一切都依赖于域名和 IP 地址，所以先在这里提一下。

### DNS

现在让我们关注真正的 HTTPS 部分。

首先，浏览器将通过 **DNS 服务器** 查询**域名的IP** 是什么，在本例中为 `someapp.example.com`。

DNS 服务器会告诉浏览器使用某个特定的 **IP 地址**。 这将是你在 DNS 服务器中为你的服务器配置的公共 IP 地址。
